Chapter2 Preparing to Install the Wide Area Application Engine
Safety Guidelines
•When the air baffle assembly is installed in the appliance, the air baffle cover
is always closed.
•Microprocessor socket 2 always contains either a microprocessor baffle or
a microprocessor.
Working Inside the WAE with the Power On
The WAE is designed to operate safely with the cover removed for short periods
(less than 30 minutes). You might need to remove the cover while the power is on,
for example, to observe the Light Path diagnostic LEDs when troubleshooting.
When you work inside an appliance that is powered on, follow these guidelines:
•Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts
before working inside the appliance; do not wear cuff links while you are
working inside the appliance.
•Do not allow your necktie or scarf to hang inside the appliance.
•Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting
wristwatches.
•Remove items from your shirt pocket (such as pens or pencils) that could fall
into the appliance as you lean over it.
•Avoid dropping any metallic objects, such as paper clips, hairpins, or screws,
into the appliance.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the appliance. To prevent
static damage, discharge static electricity from your body before you touch any of
your system’s electronic components. You can do so by touching an unpainted
metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
•When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the antistatic packing material until you are
ready to install the component in your system. Just before unwrapping the
antistatic packaging, be sure to discharge static electricity from your body.
